11 Claims.

This is a divisional application from the original filed on December 1, 1933, Serial Number 700,433 for Hygienic container.

My invention relates to a sealed, glass, by-

5 gienic container or ampuls.

Among the objects of my invention are to provide a container so constructed that liquid may be withdrawn therefrom with the danger of contamination minimized; to supply an ampul with means for catching the broken glass and preventing it from falling into the liquid to be used, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

Referring to the drawing Fig. 1 is a front sectional view of my invention showing a floating trap and a narrow tube; Fig. 2 is a front sectional view showing a different form of trap and a tube having an enlarged bottom portion.

It is obvious, of course, that any one of the traps may be used with any one of the forms of tubes, and while I have shown herein preferred embodiments of my invention yet I wish it understood that the same are susceptible of modiflcation and change without departing from the spirit of my invention.

My invention comprises a one piece, sealed, hollow, glass container I having a hollow body member ll substantially filled with liquid I2. A tube I3 is connected to the inside of the neck [4 of the container [0 and extends down into the body member H but ends short of the bottom of the container l0. An air or vacuum space I5 is left above the normal liquid level in the container. The tube [3 has on one side thereof an air inlet l6 adjacent the level of the shoulders I! of the container, and a liquid inlet l8 at its lower end and on the side opposite the air inlet l6. A stop member 19 or H! is placed within the tube l3 at the bottom thereof and adjacent the liquid inlet [8. Placed in the neck I4 is a trap 26 which has a receiving portion 2| in Fig. 1 and 2| in Fig. 2, and a handle 22. The trap 26 floats on the liquid as shown in Fig. 1. The trap may also be provided with an anchor 23. Another embodiment instead of floating is held by arms 24 to 'turns 25 within the neck [4.

As shown in Fig. 2 the tube [3 may have an enlarged lower portion 26 with the liquid inlet [8 at the side opposite the air inlet l6.

In use my invention is particularly applicable to ampuls or phials filled with medicated solution. The container. is ordinarily of sealed glass and is opened by breaking the top 21 or 21 of the neck M. In the sealed glass containers heretofore used there is the likelihood of glass particles from the breaking of the top falling into the container and contaminating the liquid therein. With my invention the trap 26 positioned above and covering the liquid receives any glass particles so dropped into its receiving portion 2!. The trap having served its purpose is then removed by using handle 22. The ampul is then ready for the withdrawal of the liquid contained therein. Ordinarily such liquid is used for intravenous or subcutaneous injections and it is important that every precaution be taken to insure a pure solution. The air coming in the neck I4 presses down through air'inlet l6 and forces liquid into liquid inlet l8 into tube IS. The user inserts his needle into tube 13 for the withdrawal of solution for the injection. Any foreign bodies in the liquid will tend to sink to the bottom ofthe container which acts as a sediment chamber 28. Other foreign bodies, if lighter, would float on the surface of the liquid. It is, therefore, apparent that the safest place for the withdrawal of liquid would be above the sediment chamber 28 and below the top of the liquid. My tube l3 accomplishes this result by ending short of the bottom of the container and having the liquid inlet l8 above this point and, of course, below the liquid level. The stop member I9 prevents the needle from touching or withdrawing liquid from the sediment chamber 28. Since all of the liquid is never used my tube insures the withdrawal of that portion of the liquid which has the least likelihood of containing foreign bodies. Therefore, my invention minimizes the danger of contamination.

The enlarged lower portion 26 of the tube l3 increases the capacity of the tube so that a greater amount of liquid may be withdrawn by one insertion of a needle. The enlarged portion if only partly filled at the time the ampul is filled may act to receive liquid which has expanded by the heat. The bottom of the enlarged portion 26 may also act as a secondary sediment chamber, and of course as a stop member.

Having thus described my invention, I claim:

1. An ampul from which liquid may be hygienically withdrawn comprising a hollow body member having a neck and a sealed breakable top integral with said body member and neck,"

vent the withdrawal of liquid at both the bottom and top level of said body member, and a removable trap within the neck of said ampul for catching and holding any particles of glass which fall within said ampul after the top of said ampul has been broken.
